• Sommario/riassunto: This publication by the International Atomic Energy Agency addresses the challenges and methodologies for selecting, assessing, and qualifying commercial industrial digital and control equipment for use in nuclear power plant applications. It focuses on the justification of digital commercial off-the-shelf (COTS) devices, highlighting their appeal due to reduced costs and rapid market availability, while emphasizing the need to mitigate risks of systematic failures in nuclear safety applications. The book outlines strategies for COTS device justification, key assessment steps, and change management practices, supported by examples from various Member States. Intended for regulatory bodies, licensees, and device assessors, it provides a framework for improving COTS device justification processes.
